Ebtech custom isolation transformers
They are included to prevent ground loops.

Independent shopping perspective
Morley’s ABC Pro is a switcher/combiner for sending one instrument signal to three output sources, then choosing individual outputs or a combined route. Its isolated channels are specified to prevent crosstalk and bleed-through, while Ebtech custom isolation transformers target ground loops. Silent switching avoids pops as routes change. Polarity-reverse and ground-lift switches, LED indication, and a cold-rolled steel housing round out the pedal. Power comes from a 9V battery or adapter.
